| 摘 要： | 本文阐述了药用植物化感自毒作用的概念、产生机理和作用特点,指出药用植物的药用活性成分与化感自毒物质的同源性是药用植物栽培中连作障碍与化感自毒作用更重要的根本原因.文章分析了连作障碍产生的原因与药用植物化感自毒作用的关系,结合作者运用DGGE和T-RFLP技术对根际土壤微生物区系的系统研究结果,提出综合运用农艺措施减缓连作障碍与化感自毒作用的危害.

| Abstract: | In this paper, the concept, mechanism and action mode of allelopathic autotoxicity of medicinal plants were discussed. The study identifies that the basic reason for the continuous cropping obstacles and allelopathic autotoxicity of medicinal plant is the homology of autotoxic-allelochemicals and pharmaceutical active substances.Accordingly, the relationship between the causes of the obstacles and the autotoxicity of allelochemicals in medicinal plants are also analyzed. Comprehensive agronomic methods based on rhizospheric soil microflora systems research using DGGE, T-RFLP and other related techniques are proposed. This reduces the inhibiting effect of continuous cropping obstacles and allelopathic autotoxicity |
